TL;DR
This paper studies how an atom confined inside a finite-width fullerene experiences enhanced photoabsorption due to surface plasmon modes, revealing significant dynamical screening effects near specific eigenfrequencies.
Contribution
It introduces a model for dynamical screening of an atom within a finite-width fullerene, highlighting the role of two surface plasmon eigenmodes.
Findings
Large enhancement of photoabsorption near surface plasmon eigenfrequencies
Presence of two distinct surface plasmon modes due to finite fullerene width
Dynamical screening significantly affects atomic response within the fullerene
Abstract
This is an investigation on the dynamical screening of an atom confined within a fullerene of finite width. The two surfaces of the fullerene lead to the presence of two surface plasmon eigenmodes. It is shown that, in the vicinity of these two eigenfrequencies, there is a large enhancement of the confined atom's photoabsorption rate.
